摘要：: PROBLEM TO BE SOLVED: To improve the calculation efficiency in analysis or the like of a tire by a numerical analysis method such as a finite element method (FEM) or the like. SOLUTION: A tire cross section basic model including a dummy element capable of easily creating tire models having a plurality of shapes and different structures are read (step 220); a tire member constituting the tire model is set (step 222); a material constant such as elastic modulus that does not appear as a behavior when the tire material deforms is set to the dummy elements (step 224), and a tire model is created (step 226 and 228). Therefore, in modeling the tire, the plurality of shapes and structures are represented only by varying the material constant of the tire model including the plurality of dummy elements without adding or deleting an element, and the calculation cost can be reduced, namely the calculation time can be shortened.
